Household Behavior under Alternative Pay-as-You-Throw Systems for Solid Waste Disposal
研究了美国马里埃塔市两种按量收费垃圾处理方案（按垃圾桶收费和按垃圾袋收费）对家庭垃圾排放量的影响，发现按袋收费减量效果更显著（36%），且带来居民节约和社会福利提升。
In 1994, residents of Marietta, Georgia, participated in a pay-as-you-throw solid waste demonstration project. Rather than pay a fixed monthly fee for collection, half of the residents paid a fee per reusable trash can, and half paid for each nonreusable trash bag collected. Data from both a sample of households and citywide totals indicate that the programs significantly reduced waste set-outs, even after accounting for increases in (unpriced) recycling. The bag program caused larger reductions (36%) than the subscription can program (14%). Rough estimates of the program indicate both savings for residents and social welfare increases.
